About a month ago I bought a bag of treats for my puppy (cracker-like, bone shaped). But when I got home I discovered that the bag said it was suitable for puppies 6 months old and older.
I don't mind storing the treats for some time (until he's 6 months old) but it got me thinking:
What makes a treat only suitable for a certain age?
I would assume nothing there would be toxic, but perhaps something in the ingredients is hard to digest for a young stomach?
